In order to upgrade a machine that can not successfully upgrade to 10.4 I downloaded and burned the 10.04.1 iso image off the ubuntu alternate download site. In my first attempt I unsuccessfully burned the image with it failing at the very end. I did perform an md5sum on it and received the precise output I got from my second burn attenpt which DID complete successfully. Here is the output:
md5sum: ./casper/filesystem.squashfs: Input/output error
./casper/filesystem.squashfs: FAILED open or read
md5sum: WARNING: 1 of 62 listed files could not be read
I did research this last night and it seems the common wisdom was to reburn the iso (which I did twice) or copy down the iso again. This I also did and it came down precisely, bit for bit, the same as the first one. Here are the two cksums
walt@cor720:~$ cksum /tmp/ubuntu-10.04.1-desktop-amd64.iso
1873051951 719472640 /tmp/ubuntu-10.04.1-desktop-amd64.iso
walt@cor720:~$ cksum Desktop/ubuntu-10.04.1-desktop-amd64.iso
1873051951 719472640 Desktop/ubuntu-10.04.1-desktop-amd64.iso
The precise image is found on page
http://www.ubuntu.com/desktop/get-ubuntu/alternative-download
And the iso itself is:
ubuntu-10.04.1-desktop-amd64.iso.torrent
Is there something wrong with this image on the website or is the error about 1 file being unreadable (could that also mean missing?) be erroneous?
I would hate to start an install with a questionable source only to have it die at an unrecoverable point.
Thanks,
Walt
